FIELDIN G SNEDIGAR, OF ELKADER, "IOXVA.

SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 280,528, dated July 3, 1883.

Application filed October 17, 1882.

T 0 all whom it may concern:

Be it known'that I, FIELDING SNEDIGAR, of Elkader, in the county of Clayton and State of Iowa, have invented a new and Improved Snow-Plow, of which the following isa full, clear, and exact description.

The object of my invention to facilitate the removal. of snow from railway-tracks.

The invention consists in a car provided witha plow and with two long arms proj ecting from the front, to which arms transverse and vertical cutters are attached at the ends, whereby when the cutters are forced into a bank of snow they cut the bottom and sides of a block of snow, upon which a hoe attached to arms pivoted to the car. is dropped and cuts the end of the block of snow, which is withdrawn by backing the locomotive, and is then pushed to the sides of the track by the plow as soon as the locomotive is moved forward.

Reference is to be had to the accompanying drawings, forming a part of thisspecification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal. elevation of my improved snow-plow. Fig. 2 is a plan view of the same. Fig. 3 is a cross-sectional. elevation of the same on the line 00 00, Fig. 2.

The plow A, which is provided with a double mold-board and an inclined central ridge or cutter, B, is attached to aboX-car, G, which is coupled in front of the locomotive. Two long side bars, D, are pivoted to the side of the small car 0, and at the outer ends they are connected by a transverse horizontal cutter, E, which rests on the rails F, and is guided by clips I, attached to the under. side of the cutter and resting against the sides of the rails. Vertical cutters G, having their lower ends flared forward, are attached to the ends of the transverse cutter E. A cutter or hoe, H, is attached to the ends of two long arms or bars,

(No model.)

J which are pivoted to the sides of the car and which are connected by a bail or cros piece, K, to which is attached a rope, I1, pas

ing over a pulley, M, on the cross-piece of tv strong standards, N, on the car 0. The low end of the rope is attached to a Windlass, which can be operated byhand or steam powe The operation is as follows: The cutters and G are driven into the packed snow, t] cutters cutting the sides and bottom of a blo of snow. Then the hoe or cutter H is droppr and cuts the front end and sides of the bloc If the engine is then backed, the hoe H draw out the block of snow, which is then drawn some place where it can be dumped at the sid of the tracks. The hoe H is then raised, a1 then the engine is moved forward, upon whi the plow A cuts into the block and throws to the sides of the track. The engine conti ues to run forward and forces the cutters E into the bank of snow, the hoe H is droppe and another block is removed in the same ma ner as described above, and so on until t] tracks are clear. In making curves the 11 must swing with the cutter-bars, so as to: ways drop in front of them.

Having thus described my invention, I clai as new and desire to secure by Letters Patent In devices for removing snow from railwa tracks, the combination of side and botto cutters, G G E, adapted to run. on the rails, sequent drop-hoe, H, adapted to cut the fro end and sides of the snow-block, and the do ble-molchboard plovt A, having the centi ridge or cutter, 13, whereby the snow will fii be cut at the bottom and sides, then cut off the sides and front end, and then thrown in two divisions, one to each side of the roa as described.
